ATOMIC ORBITALS Schrodinger’s Quantum Mechanics Model
ORBITALS – AREAS WITHIN ATOMS WHERE THERE IS A HIGH PROBABILITY OF FINDING ELECTRONS Principal Energy Levels - A region around the nucleus of an atom where the electron is likely to be moving. (n = 1, 2, 3, 4, etc.) Number 1-7 on periodic table down side.
ENERGY SUBLEVELS Energy sublevels can be thought of as a section of seats in a theater. The rows that are higher up and farther from the stage contain more seats, just as energy levels that are farther from the nucleus contain more sublevels. Sublevels are labeled s, p, d, and f according to the shapes of the atom’s orbitals.
ATOMIC ORBITALS Each orbital may contain at most 2 electrons. Each energy level may contain at most 1 s orbital, 3 p orbitals, 5 d orbitals, and 7 f orbitals. (all odd numbers).
